Yes, this is just the value that got negotiated according to the line
conditions at the time. There's not likely to be much about you can do
about it. There are often all sorts of things you can tweak but in the
end that's a pretty reasonable/normal connection speed for a 56K modem so
you probably won't manage to improve it much.
In fact I understand that many ISPs set their dialup servers to prevent
connections over about 48-50k anyway, because above that it's too
unstable. I have experienced this myself. I have a cable phone line here,
connecting directly to the ISP of the cable company. Hence I have a very
clear path and can get connections >52000! But if I take the computer
elsewhere and dial up to the same ISP from an old BT (the main telco here)
phoneline, then although it will connect quite fast I get line drops
constantly. It would therefore seem that this particular ISP have set
their servers to let you connect as fast as possible (because in many
cases people will be dialling up from their own cable lines, and can do
this). But you can see straight away that if most ISPs did this they
would immediately get lots of complaints about dropped lines etc., which
is why they put the max speed down a bit. I did the same thing when using
this modem on a BT line - I tweaked the modem settings to force it to
connect at 45k max, and then the line was much more stable.
